With the Custodes on the rise we are going to take a look into the outlook and training of the first modified warriors created by the Emperor!
Via our good friends at Lexicanum
Although the Custodes were among the first modified warriors to be created by the Emperor, they were never intended to be part of a conquering army; such a role was to be filled by the latter Astartes armies. This is revealed both in their mindset and training, where the Custodes do not fight as brothers and as a greater whole but rather as individual warriors. This is in stark contrast to Space Marines, who employ a high degree of teamwork and collective tactics in battle. At least some Astartes look down on the Custodes for these tactics, and it may be that this was deliberately designed so that they shared a bond with none but the Emperor himself.
While Custodians share a genetic kinship with one another within the formation, they do not foster the same spirit of brotherhood that is instilled within the Astartes in order to function together as a unit. Indeed, each Custodian prepares and inspects his equipment individually, rather than on military parade The individuality of each Custodes is further promoted by the fact that the processes required to produce them is not as refined or as simple as that of the Astartes and thus are not “mass-produced” as the Astartes are; meaning that each Custodian is a unique investment for the Imperium. One ritual that the Custodes do share is the recognition of mighty deeds, manifested in the awarding of names, which are added to the Custodian’s title to represent the actions he has performed in service to the Emperor (Constantin Valdor obtained 1932 names prior to the assault on Terra). Such names were inscribed onto the inside of the warrior’s battle armour as marks of individual pride.
The training of the Custodes also differed immensely from the Astartes, being bodyguards rather than soldiers. It is clear from their Blood Games that Custodians are trained in the arts of assassination – both improvised and advanced – in order to counter possible assassination attempts to the Emperor. It is common for several Custodians to be on detached duty for these Blood Games so that the organisation remains vigilant against developing threats. Furthermore it is clear that the Custodes are also well versed in the political etiquette of Terra, and have been known to act outside of Imperial Law, to infiltrate influential Noble Houses and to investigate any potential threats (a role that an Astartes would never be expected to fulfil.)
This aspect of the Custodian mindset is advantageous, given that the Captain-General often shares a seat with the High Lords of Terra, which thus allows him to navigate the political maneuverings of the Imperium’s various agencies, while still remaining an awe-inspiring warrior.
